button is pushed, the indoor unit Nos. in the group control operation are dis-
played in order.
(The settings stored in the EEPROM of the P.C. board for indoor unit servicing are the factory-set values.)
Specify the indoor unit No. with its P.C. board replaced to the P.C. board for indoor unit servicing.
(You cannot perform this operation if “
” is displayed.)
Step 3 Select the CODE No. (DN) can be selected by pushing the
/ button for the temperature setting.
• Set the indoor unit type and capacity.
The factory-set values shall be written to the EEPROM by changing
the type and capacity.
1. Set the CODE No. (DN) to “
